the movement of molecules occurs

Detailed explanation-1: -a characteristic common to both diffusion and active transport is movements of molecules, energy requirements, oxygen is moved or the molecules move from low concentration too high concentration.
Detailed explanation-2: -Both facilitated diffusion and active transport share the following characteristic, in that they both require the use of transport proteins to move the particular solute across the cell membrane.
Detailed explanation-3: -Answer and Explanation: Facilitated diffusion and active transport have, in common, the fact that they both use transport proteins. In active transport, protein pumps move molecules from a low concentration to a high concentration.
Detailed explanation-4: -Active transport is not the same as facilitated diffusion. Both active transport and facilitated diffusion do use proteins to assist in transport. However, active transport works against the concentration gradient, moving substances from areas of low concentration to areas of high concentration.
Detailed explanation-5: -The process of diffusion and active transport are both used to move materials from one location to another. Diffusion moves materials through a medium by allowing them to move freely and randomly. Active transport, on the other hand, uses energy to move materials through a medium.
